We do not therefore limit ourselves narrowly to the materials above set forth or to the eX- act proportions of the same, but claim,broadly, the use of compounds to produce these effects, which are novel in this art.

It will be noted that the sugar or its equivalent is the leading factor in producing the eifect of after-hardening which renders the article incapable of being readily softened by heat, and it will also be noted that the action of the glycerin and glue in combination with the filling materials enables us to produce a depth of outline and configuration hitherto unattainable.

Having thus described our invention and.

its use, what we claim is 1. The herein-described process of treating paper to render it ductile, consisting of subjecting the same to a preparation consisting of a glue, a saccharine substance, white lead and glycerin, substantially as and for the purposes set forth.

2. The herein-described process of treating paper to render it ductile, consisting of subjecting the same to a preparation composed of a glue, a saccharine substance, red lead and glycerin, substantially as and for the purposes set forth.

3. The herein-described process of treating paper or cellulose material, consisting of subjecting the same to a solution consisting of a fish-glue, a saccharine substance, white lead, a filler, and glycerin, substantially in the proportions and for the purposes set forth.

4. The herein-described process of rendering paper or cellulose material pliable and ductile, consisting of subjecting the same to a solution of common glue, fish-glue, sugar, white lead, talc and glycerin, substantially in the proportions and for the purposes set forth.

5. The herein-described process of forming wood-pulp paper, or other fibrous material, consisting of treating the same with a solution composed of a glue, a saccharine substance, white lead, a filler and glycerin, and drying the same, subjecting the same to heat to render it pliable, and then subjecting the same to pressure or other means of forming to produce the desired configuration, substantially as and for the purposes set forth.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
